  • Device for detaching an electrolytically precipitated metal sheet from a cathode
    Patent number: 3996127
    Abstract: Electrolytically precipitated metal sheets, such as copper, nickel or zinc sheets, are detached from a base plate having worked as a cathode during precipitation and being rigidly held in a vertical position. Firstly, the upper edge of the metal sheet is detached entirely or locally by the aid of a blade system and, thereafter, said detached edge portion is grabbed with gripping means and pulled outwards essentially in a horizontal direction until the entire metal sheet is detached from the base plate. To facilitate the initial detachment an insulating tape or similar may be glued to the base plate at the solution level before precipitation. The gripping means may be connected to essentially horizontal guide means provided with driving members for creating the pulling force.
    Type: Grant
